Recycling of Mill Scale Into High‐Purity Iron Through Hydrogen‐Based Reduction

steel research international, EarlyView.
Mill scale, an iron oxide–rich steel by‐product, is difficult to recycle due to impurities. This study evaluates hydrogen‐based direct reduction and hydrogen plasma smelting reduction as low‐carbon recycling routes. Impurity segregation limits reduction kinetics. Direct reduction achieves 92% conversion in 180 min, while plasma reduction reaches 91% in

Barriers to Steel Decarbonization

steel research international, EarlyView.
Main identified barriers to steel decarbonization Carbon dioxide (CO2) emissions are a leading contributor to global climate change, necessitating urgent mitigation strategies. While various metrics—such as total national emissions, per‐capita output, and historical contributions—define responsibility, determining accountability remains complex ...

Foamed Concrete Sealing Materials for Coal Seam Gas Drainage Boreholes: A Review

Safety Science and Technology, EarlyView.
This study investigates the sealing performance of foamed concrete in gas drainage boreholes. By comparing leakage pathways (a, c) with sealed systems (b, d), the research demonstrates how foamed concrete effectively fills mining‐induced fractures and resists deformation.

The “We” and “Me” of Identity in Hazardous Industry Organizations: Face Work Tactics Among Practicing Engineers

Symbolic Interaction, EarlyView.
In this paper, we use Goffman's notion of “face work” to examine how pipeline engineers perform and present their working selves as competent experts. Our analysis identifies various faces and face work tactics, including a focus on professional judgment, actively selling one's expertise relative to others, protective self‐deprecatory strategies, and ...

Thermal Degradation and Thermal Decomposition of Plasticized PVC Including POSS Additives for PVC Compounds: Mechanisms, Impact, and Performance of Standards

Journal of Vinyl and Additive Technology, EarlyView.
Additives' structures. ABSTRACT Poly(vinyl chloride) has been a key polymeric material since its commercial production in 1931, demonstrating versatility across numerous industries due to its compatibility with various additives. PVC's inherent properties, flame retardance, durability, and recyclability make it ideal for building and construction ...

Climate exposure drives firm political behavior: Evidence from earnings calls and lobbying data

American Journal of Political Science, EarlyView.
Abstract When and how do firms engage in climate politics? We argue that regulatory concerns, business opportunities, and physical risks activate policy preferences and lobbying efforts. We measure firm‐level exposure to opportunity, regulatory, and physical aspects of climate change based on discussion in quarterly earnings call transcripts for 11,705

Fighting fire with fire: Prebunking with the use of a plausible meta‐conspiracy framing

British Journal of Psychology, EarlyView.
Abstract Prebunking can be used to pre‐emptively refute conspiracy narratives. We developed a new approach to prebunking – fighting fire with fire – which introduces a plausible ‘meta‐conspiracy’ suggesting that conspiracy theories are deliberately spread as part of a wider conspiracy.

Erosion Potential of Commercial Fluoride‐Free Mouthwashes on Dental Hard Tissues

International Journal of Dental Hygiene, EarlyView.
ABSTRACT Purpose Mouthwashes often present acidic pH, which raises concerns about their potential contribution to erosive tooth wear. This study evaluated the erosive potential of commercial fluoride‐free mouthwashes using a screening method.

Influence of Tapered‐End and Round‐End Bristle Designs on the Abrasive Enamel Wear Using Toothpastes With High Discrepancies in Abrasiveness

International Journal of Dental Hygiene, EarlyView.
ABSTRACT Purpose The aim of this in vitro study was to investigate the influence of bristle end design of toothbrushes and the relative enamel abrasivity (REA) of used toothpaste on the resulting abrasive enamel wear. Materials and Methods A total of 160 bovine enamel samples were allocated into eight groups (n = 20) and surface topography was recorded
